About

Hello! I'am Kelana Chandra Helyandika

I am deeply passionate about backend development, constantly exploring the latest technologies and innovations in the field. While I have a strong foundation in Node.js, my recent focus has been on mastering Golang, particularly with the Gin and Fiber frameworks, to further enhance my backend capabilities.

With a solid understanding of database management, I have hands-on experience with both relational databases such as MySQL and PostgreSQL, and NoSQL solutions like MongoDB and Firebase. Additionally, I have expanded my skill set to include frontend development using frameworks like CodeIgniter, showcasing my adaptability across the development stack.

My expertise also extends to software testing and quality assurance, where I leverage tools such as Jest for unit testing, K6 for performance testing, and Playwright for API automation testing. This combination of backend expertise, database management, and testing proficiency underscores my commitment to delivering robust and scalable solutions.
